There are many different types of stone available today.

After raw material cut into big slab, it usually use these tools in the followings to process into polished slab.

The slab which have sawn is have kerf, and its surface is accidented.

50# strike the flatness with the visible kerf surface.

200# the color of material doesn't change, and lackluster, no slash,and the surface is levelled off also with slight kerf, it such as honed.

400# the color of material becomes only a little dark, but lackluster, no slash

500# the color of material becomes a little dark, but lackluster, no slash, it such as smooth (inferior and smooth),

800# the color of material becomes more darker than 500#, have a little luster, no slash

1500# the color of material becomes more darker than 1000#, have more luster than 800#, no slash

Resin polished process into polished slab, and luster will different because of different materials.

The above processing we generally called machine polished.

If the edges of granite need to polished, it usually processed by handwork. The processing sequences are #50, #100, #200, #400, #800, #1500, #3000, buff.

If edges smooth, just processed from 50# to 800#.This processing we called manual polished.



If process the edges into honed, generally use the grinding wheel 70# . Grinding wheel is also applicable to all kinds products which edges chamfered. If the chamfer need to smooth, just use 80#.

Grinding tools for marble: 60# -- 400# -- 800# -- 1200# -- polishing
